This or that...This or that...
http://bboyflexi.imeem.com/music/j-_J-4tV/the_choice_is_yours/ The choice is
yours!
Is there a list of rules somewhere that define where this is that or the
reverse? Or a very detailed description of what you're left with after a
selector is run and the object is passed to the next link in the chain?
It's apparently arcane knowledge :) I see that in the keypress you have
function (e) - where does e come from and how does it get passed?
Much thanks for taking the time - great example and I *think* I get it. The
only things I'm not understanding are why you used #test as the first
selector, since that is the form ID, and why the before statement was added
last - or does that matter?
And why would you use a class as an identifier? it might be best to change
the class to turn the text red/green rather than changing style elements.
You might want to make the text bold too, for example. I'm not opposed to
it, just trying to understand the thought process. Would changing the class
break that selector?
